Problems solved by technology

And many potential communication risks need to be quantitatively evaluated on parameters such as communication nodes and channels during the operation of the power communication network to find unreliability problems, risk events and potential risk threats in the power communication network
In addition, the current power communication network mainly adopts optical fiber ring network or redundant channel to ensure the reliability of the power communication network. The network bandwidth utilization rate of this method is low, and there may be network bandwidth resources when a large number of communication failures occur concurrently. tension so that important businesses cannot be effectively restored and protected

Abstract

The invention relates to a power grid communication service oriented communication risk early warning and risk avoidance method. The method comprises a communication risk early warning process and a risk avoidance process; the communication risk early warning process comprises following steps: carrying out risk parameter quantified assignment to optical communication devices and optical channels; setting service weights according to the importance degrees of the borne power grid communication services; and determining the risk probabilities of the communication risks of the services. The risk avoidance process comprises following steps: with respect to the service communication channels which have relatively high communication risk probability values and need route optimization, carrying out priority sorting to the service communication channels according to risk existing degrees; constructing a delay information matrix list; and searching new service routes to the services which have risks and need the route optimization. According to the method of the invention, timely and effectively early warning is carried out to the communication risk probabilities in the power service; automatic route optimization is carried out to the service channels with the communication risks; and the interruption risks in the power grid services are avoided timely.

Description

Technical field: [0001] The invention relates to a communication risk early warning and risk avoidance method, and more particularly to a communication risk early warning and risk avoidance method for grid communication services. Background technique: [0002] In the field of power communication, the power communication network carries a large number of production control services and information management services, including not only the construction of SG-ERP system, centralized data disaster recovery center, but also the wide application of video surveillance, video conferencing and GIS information Such high-bandwidth services also include real-time control services for power grid production and operation with high importance, such as relay protection, stability, and wide-area vector measurement. With the increasing dependence of the power system on power communication, the impact of time delay, risk and failure of the power communication network on the power system is a...
